CARL PAUL LUDWIG, OF BIRMINGHAM. ALABAMA.

APPARATUS FOR DRAWING AND HANDLING COKE AND LEVELlNG coAL,"

2?) mil whom it may concern:

Be it known that I, CARL PAUL Lunwre, a

citizen of the United States, residing at Birmingham, in the county of Jefferson and State of Alabama, have invented new and useful Improvements in Apparatus for Dra wing and Handling Coke and Leveling Goal, of which the following is a specification. I

My invention relates to impro vements in a convertible coke-pulling, coalle veling, and oven-cleaning machine adapted to be mounted on a car and moved on tracks in front of the coke-o vens.

The chief object of my invention is to provide a machine comparatively simple in construction and operation which is provided with a motor-operated draw-bar or coke-pulling arm adjustable angularly and laterally by hand devices, all of which are disposed within In other words, I provide a motor-reciprocated drawbar adapted to be swung on vertical and horizontal axes and to be moved laterally by means independent of each other and said motor which are controllable from one point and capable of contemporaneous operation guring the reciprocatory movements of the It is a further-object to provide a Il0\6l form of rake-head for the draw-bar and to pro vide it with antifriction side rollers to protect the side walls of the ovens. To adapt this bar for use as an oven-cleaning device, I

provide an attachment for the rake-head which gives it the straight bottom edge'required for these purposes.

My invention further comprises impro vements in the operating and adjusting mech anism for the draw-bar which comprises a rotatable platform and a swiveling guide for the bar mounted thereon and provided with an adjustable stop to limit the travel of the bar into the oven and prevent-it striking the back wall. This guide is light in weight, but of considerable length, being adapted to carry idler-p alleys for the operating cable or cables which connect to the draw-bar and move it back and forth in the guide.

An important object of my invention is to provide a receptacle adapted toreceive andpreferably to screen the coke as it is drawn from the oven and when loaded to be lifted by laterally-swinging part of the coke-p ulling apparatus and moved to a point of discharge,

where it is dumped. This provides a simple and effective apparatus to handle and load the coke.

My invention further comprises the novel construction and combination of parts hereinafter more particularly described, and illus- 6o trated in the accompanying drawings, where- Figure 1 is a side view of myimproved mechanism, showing the drawbar and guide in cross-section. Fig. 2 is a side elevation, the draw-bar and guide being broken to illustrate both end portions.

. According to thepreferred construction of 5 my invention, as illustrated in the drawings, I provide a platform or turn-table 1, rotatably mounted upon a car '2, provided with wheels 3, which move on a track 4. Atone end of the car I provide a vertical standard 5, at the top of which a hand-wheel 6 is connected to a sh aft 7 suitably journaled in this standard and carrying a sprocket-wheel 8, which drives a chain 9. This chain passes through an opening in the floor of the car and 10 5 passes around a sprocket-wheel 10, suitably ournaled in the side beams of the car. This sprocket-wheel 10 drives a sma ler sprocketwheel 1 1r',,; which....by. means of l a chain: 12 drives. a sprocket-wheel 13 ,ffixed on a l-axle 14. Sproeketwheels 15 omtheaaxles le and 16 are connected'by a chain 17'. By turn- 5 ing the hand-wheel fi the car'g'2 may be moved.-

The bearing for the shaft 73 is formed by lateral recesses in the sides of the frames 22 above the extensions 68, the shaft being held in position by bearing-blocks 79, bolted to the frames and closing the lateral open- 111 s.

TVhen pressure is admitted to the motor 55 to reciprocate its piston and, through the connections described, to rotate the drums 74 and 75, it will be evident as cable 76 is wound on its drum to move the draw-bar for- "ward the cable 76 will-be unwound to permit the bar to move, and vice versa when the motor is reversed. By these means the drawbar may be moved in and out in its guide 25 for the purpose of drawing the coke or leveling the coal, as will be hereinafter described. To limit the forward movement of the drawbar, I provide a stop 80, adjustably connect-.

ed to the guide 25, near its forward end. It may be set to any desired position on the guide, so as to engage a spring-pressed bufferarm 81, provided at its outer end with a cross-pin 82, against which the spring 83 bears. This block 77, as shown in Fig. 10, is preferably formed by two plates bolted -to opposite sides of the draw-bar 26, the arm 81 being mounted to have a limited sliding movement between these plates when pin 82 engages the stop-block 80 and compresses the spring to cushion the arm. At the front end of the draw-bar I'bolt or otherwise secure two metal bars 85, which are bent outwardly to each side on a sli ht curve. The

- outer end of each bar is bifurcated to form two arms 86, which'are bent to form bearings for a roller 87. An inverted-V-shaped rakehead is bolted to these bars 85 and is of such a width that the rollers 87 project beyond it to prevent it striking the sides of the oven.

This rake-head is particularly adapted for breaking down the coke in the oven and drawing it out. It may also be used for leveling the coal in the oven, or, if desired, a detachable plate 89, having-a straight bottom edge and a bent flange 90 at its upper edge, may be slipped over the end of the rake-head and secured by abolt passed through an opening 91 and engaging the rake-head. The flange 90 of this plate is curved to conform with the contour of the rake-head when slipped over the top thereof and forms a device which is adapted both for leveling the coal and for cleaning out the oven after the coke has been drawn.

In practice the operator, by means of the handwheel 6, moves the car op osite the oven 92, which is illustrated in 'the orm com monly known as the beehive oven. When the draw-bar comes opposite the ovendoor, pressure is admitted to the motor 55, so as to cause it to rotate the drums 74 and 75 in a direction to move the bar into the ovendoor. While this movement is taking effect the handwheels 6, 45, and 47 are grasped and by turning them and by operating them one at a time or simultaneously the rake-head is swung or moved to any desired position in the oven and caused to, engage a section of the coke, after which the motor is reversed and the bar drawn outwardly under the independent or joint control. of the handwheels. By this means while the motor is moving the draw-bar into the ovenand'drawing it out the operator maintains a control of the bar which'enables him to handle it with as much ease and precision as if the coke were being drawn direct by manual means, the motor being called upon solely to furnish the power for reciproeating the draw-bar. It will be noted that the movement of the car on the track enables the draw-b ar to reach all portions of the oven and that the antifriction-rollers 87 prevent the sides of the rake-head striking or injuring the walls of the oven. To prevent the end of the draw-bar striking the oven, the stop 80 is provided and so disposed on the. guide 25 that it arrests the travel of the bar at the proper point to prevent injury to the back Wal of the oven.

To convey coke to any desired point of dis v charge, I provide a receptacle or coke-box 93, having a screen bottom formed by the bars 94 and a bail 95, adapted to engage a hook 96, depending from the pulley-block 30 at the forward end of the guide 25. This receptacle is leaned against the oven, as seen in Fig. 8, in position to receive the coke as it is drawn out by arm 26 and screen it. By catching the bail over hook 96 the receptacle may be lifted and swung around to any desired point of discharge which ma be over a car 97. To dump the contents 0 the receptacle, I connect a dumping-rope 98 to its bottom and pass it over a pulley 99, journaled between the plates of the stop 80. A hook or catch 100 is provided at the end of the rope and adapted to be sna ped over the cable 78, so as to be engaged b a knot or stop. 101 thereon. When thegui e has swung the receptacle to the dumping-point and catch 100 has been snapped over the cable 78, the motor is started to draw the bar 26 inwardly. This moves cable 7 8 until the stop 101 engages the catch and draws the rope 98 in' :wardly over pulley 99, so that it lifts the re ceptacle and dumps its contents, as seen in Fine.
